Data locality and simplified deployments are the only reasons I can think of. Accumulo doesn't do anything particularly special for data locality, but typically, an HDFS client (like Accumulo servers) will (or can be configured to) write one copy of any new blocks locally, which should permit efficient reads later. This works well with Accumulo's hosting behavior, where each tablet is hosted on a single server solely responsible for its reads and writes.
